FULL PRODUCT VERSION :
java version "1.4.2"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2-b28)
Java HotSpot(TM) Client VM (build 1.4.2-b28, mixed mode)

FULL OS VERSION :
Microsoft Windows 2000 [Version 5.00.2195]

EXTRA RELEVANT SYSTEM CONFIGURATION :
Compaq Evo D51S/Intel P4 2.4GHz

A DESCRIPTION OF THE PROBLEM :
Using Drag & Drop with sources from outside the VM can/will cause the VM to crash.



STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Copy the sourcecode (HTML) below to a file

1) Start the MetalWorks Demo included with java1.4.2
2) Choose (MenuBar)File->New
3) Start IE (ver 6.0.2600.000 in this case)
4) in IE navigate to the test case

5) double click on Facilities in ie (very fast - it seems to make the difference)
6) Drag the text to any place in the demo which is not a drop target.
7) goto 5

If the cursor indicats that drop is not supprted then drop the text
the VM will then exit abruptly

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
the test (facilites) is always dropped or it fails but without crashing the vm
ACTUAL -
works some times, othertimes the VM crashes...
